Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Noisy compensator

Another comparison here to Harley, but it may be very close.

In the old days with Harley, they used a ramp type compensator very similar to what you have on your M3W's. Let's take that a bit further, Harley today uses a compensator with ramps just about like the old style. But the old bikes with their 74" to 88" size motors lasted a VERY long time.

Now that Harleys smallest Big Twin is a 103" and like mine with the 110" motors, the compensators are failing at a lot faster clip and has been a BIG problem with many riders.

So the design is okay for smaller lower torque motors, but 100" up to 120" where you guys are, is not working for Morgan or Harley.

Sad to say, I'm only repeating what's already been said here, it isn't if they fail, but when they fail.

On Harley's latest version they added a Torrington needle bearing thrust setup and they have also designed a scoop on the inside of the primary cover to collect and drip oil right back onto the bearing and ramps. So far this one is working a bit better than the last three iterations, but time will probably prove it as a failure too.

So something like the Centa with the four rubber logs being compressed back and forth with the torque pulses within the rounded slots in the inner and outer housing of the new compensator, this is probably the way to go for a long term fix.

Someone said that their Centa created a vibration. There is no way on the design to go out of balance unless one of the logs literally disintegrated and fell out. Or maybe the rubber is not forgiving enough and the vibration is actually the torque pulses coming through the driveline.

I do really wish you guy a good solution to the comp problems.

Dan your spot on with this. The compensator isn't just similar to a Harley! it f from a Harley. I get my 3W back from the factory tomorrow, complete with new chassis.
They said they get it Done within a month and fair ply it's back on time.
Report tomorrow

Matty,

have a safe and trouble free journey, hope you will be grinning from ear to ear.

Hello Matty,

Pleased to hear you will have your car back today. Enjoy the rest of the summer. You deserve it!

Best of luck with it Matty, maybe we'll have another meet at Compton Abbas in Septmber, which you will be able to enjoy properly?

More info from my dealer Revolutions in Perth. I've booked in for them to fit the grease nipple to the compensator at no cost to me. They have done several & it takes around 30 minutes.
Revolutions can & will fit the old style compensator if it fails with like for like plus grease nipple. They can do it in 8 to 9 hours & have done several as a warranty job.
If I wanted a centa compensator there would be a charge, it takes a lot longer to change to centa & there would be a cost to me but I dont know how much or if they can do it.
The factory closes this evening till Monday 4th August so I guess if you are waiting for info you will have to wait a bit longer.
Raphael, what grease are you using & how often do you need to grease it?

Tim.

My m3w is a october/2013 build,with no grease nipple...should i leave it as is until it breaks & install the centa...can grease be put from the top just behind the engine?there is a open area

There is a dilemma here. Should you extend the working life of a compromised part through diligent maintenance and have it fail just outside the warranty period? Or leave it alone and have the Centa unit fitted if/when it fails...

Personally I would want it to fail under warranty and have the upgrade installed.

I don't think you will get the Centa though. MMC will try and fit the original setup and charge you to upgrade.
